It accepts tooling with a 6 mm bore diameter and provides a projection of 75.9 mm, making it suited for reaching into workpiece features while maintaining rigidity. The adapter includes through-coolant capability, directing cutting fluid directly to the tool tip for improved chip evacuation and thermal control. With a clamping depth of 22 mm and a nose diameter of 21 mm, this holder delivers secure tool retention under high-speed cutting conditions. It is installed by qualified CNC machinists and tooling technicians in production and job-shop environments.\u003c\/p\u003e\u003cp\u003eThis adapter is used in vertical and horizontal machining centers equipped with a CAT40 spindle taper. The through-coolant feature makes it well suited for deep-cavity milling, drilling, and reaming operations where flood coolant cannot reach the cutting zone effectively. The 163.4 mm overall length allows for adequate reach in multi-axis setups without requiring extended-reach tooling in most standard applications. It is a single-piece unit packaged individually.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eCAT40 taper shank interface for direct spindle mounting on compatible machining centers\u003c\/li\u003e\n\u003cli\u003e6 mm bore diameter with 22 mm clamping depth for secure shrink-fit tool retention\u003c\/li\u003e\n\u003cli\u003eThrough-coolant passage directs fluid to the cutting edge for heat reduction and chip removal\u003c\/li\u003e\n\u003cli\u003e75.9 mm projection supports reach into recessed workpiece features\u003c\/li\u003e\n\u003cli\u003e21 mm nose diameter provides clearance in tight-tolerance setups\u003c\/li\u003e\n\u003cli\u003e163.4 mm overall length suits a wide range of standard CNC machining applications\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style shrink-fit adapter for CAT40 spindle machining centers requiring through-coolant tool holding with a 6 mm bore diameter.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation requires a shrink-fit tool holder induction heater to expand the bore before inserting or removing tooling — never attempt to press or hammer tooling into or out of the bore. Ensure the spindle and machine are fully powered down and locked out before changing tooling per applicable shop safety procedures. Verify through-coolant port alignment with the machine spindle's internal coolant supply before mounting. A qualified CNC machinist or tooling technician should perform setup and verify runout with a dial indicator after installation.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Taper\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTaper Size\u003c\/strong\u003e: CAT40\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 163.4 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBore Diameter\u003c\/strong\u003e: 6 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eProjection\u003c\/strong\u003e: 75.9 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eClamping Depth\u003c\/strong\u003e: 22 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNose Diameter\u003c\/strong\u003e: 21 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThrough Coolant\u003c\/strong\u003e: Yes\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Dimensions\u003c\/strong\u003e: 7.8 x 3.39 x 3.39 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 2.65 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 27112809\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: SECO\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 02998704\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SECO TOOLS","offers":[{"title":"Default Title","offer_id":51563836703026,"sku":"02998704","price":744.64,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/a8892f71c5506be24e144d8b8790b5fd.jpg?v=1786504528","url":"https:\/\/voomisupply.com\/products\/seco-02998704-shrink-fit-tool-holder-adapter-cat40","provider":"Voomi Supply","version":"1.0","type":"link"}
